Re: [Ftpapi] USPS address verification return values

I am trying to use the program that was posted 4 years ago for the USPS verification of addresses. My question is, how to I get the results? The program works fine and send the data to USPS and gets a response, but how do I evaluate the response? I don’t see it coming back into a variable. I am an RPG guy, with almost no XML, so I must be missing something.
Thanks very much

d address1        s             38a    inz(*blanks)

d address2        s             38a    inz('6406 Ivy Lane')

d city            s             15a    inz('Greenbelt')

d state           s              2a    inz('MD')

d zip5            s              5a    inz(*blanks)

d zip4            s              4a    inz(*blanks)
